    Abstract: A method of forming a structure having selectively placed carbon nanotubes, a method of making charged carbon nanotubes, a bi-functional precursor, and a structure having a high density carbon nanotube layer with minimal bundling. Carbon nanotubes are selectively placed on a substrate having two regions. The first region has an isoelectric point exceeding the second region's isoelectric point. The substrate is immersed in a solution of a bi-functional precursor having anchoring and charged ends. The anchoring end bonds to the first region to form a self-assembled monolayer having a charged end. The substrate with charged monolayer is immersed in a solution of carbon nanotubes having an opposite charge to form a carbon nanotube layer on the self-assembled monolayer. The charged carbon nanotubes are made by functionalization or coating with an ionic surfactant.

    Abstract: A graphene nanomesh based charge sensor and method for producing a graphene nanomesh based charge sensor. The method includes generating multiple holes in graphene in a periodic way to create a graphene nanomesh with a patterned array of multiple holes, passivating an edge of each of the multiple holes of the graphene nanomesh to allow for functionalization of the graphene nanomesh, and functionalizing the passivated edge of each of the multiple holes of the graphene nanomesh with a chemical compound that facilitates chemical binding of a receptor of a target molecule to the edge of one or more of the multiple holes, allowing the target molecule to bind to the receptor, causing a charge to be transferred to the graphene nanomesh to produce a graphene nanomesh based charge sensor for the target molecule.

    Abstract: A process comprises combining a Ce (IV) salt dissolved in a solvent comprising water with a carbon material comprising CNT or graphene wherein the Ce (IV) salt is selected from a Ce (IV) ammonium salt of a nitrogen oxide acid, Ce (IV) ammonium salt of a sulfur oxide acid, Ce (IV) salt of a lower alkyl organo sulfur acid, or Ce (IV) salt of a lower alkane organo sulfur acid. In one embodiment the Ce (IV) salt is selected from Ce (IV) ammonium nitrate, Ce (IV) ammonium sulfate, Ce (IV) lower alkyllsulfonate, or Ce (IV) trifluoro lower alkanesulfonate. A product is produced by this process. An article of manufacture comprises this product on a substrate.
